Least decentralized fund trading system and method thereof

Abstract

A least decentralized fund trading system includes a money pool database and a fund transaction processing system. The money pool database includes an accommodator account and participant accounts. The fund transaction processing system includes a fund matching module, a clearing and settlement module and an encrypted packaging module. The fund matching module matches the transaction-term orders and generates bid/ask matching information. The clearing and settlement module is to perform a clearing process and a settlement process upon the bid/ask matching information with respect to corresponding transaction-term orders and the corresponding participant accounts. The encrypted packaging module bases on a time series of the transaction record to record the transaction receipt or the balance receipt into ledger information, and the encrypted packaging module performs an encryption process upon the ledger information so as to obtain a total root encryption value. In addition, a least decentralized fund trading method is provided.
